Product DescriptionShenzhen Chenggong Trade Co., Ltd. sells Water-reducing Reinforcing
Additive for high-strength Calcium Aluminate Refractory Cement and
Refractory Concrete. Our Water-reducing Reinforcing Additive can
increase water-reducing ratio 20%-30%, can increase compressive
strength (1 day) 45 to 100% at 20oC, within 3 days can reach 70% of
benchmark concrete (without adding Water-reducing Reinforcing
Additive) compressive strength (28 day), can increase compressive
strength 30 to 50% at 28 day. After using Water-reducing
Reinforcing Additive, the performances of tensile strength,
breaking strength, permeability resisting, frost resistant,
capability of bonding steel bar, carbonization resisting, are
improved effectively. Using Water-reducing Reinforcing Additive
into steam-cured concrete, demoulded strength can be increase 40%
or more. After steam-cured, the concrete strength at 28day can be
increased about 20%, the steaming period can be reduced 1/3 or the
temperature can be debased about 20oC. When mixing Water-reducing
Reinforcing Additive into the cement, and not increasing the water
quantity, the slump constant of concrete can be increased from
2-5cm to 15-25cm, and the strength does not fall. When using
Water-reducing Reinforcing Additive into Calcium Aluminate Cement
to make refractory concrete, clearly to increase the concrete
strength at high temperature, and there is no any blight for the
concrete. Recommended quantity of Water-reducing Reinforcing
Additive is usual 0.5 to 1.0% of cement weight, for high-strength
concrete, 0.8 to 1.2%.

Product Featurewhite powder; to can increase the strength of refractory cement and
refractory concrete; to can decrease the requested water quantity.
